电子效应精准调控的纳米金催化剂在低碳多元醇选择性氧化研究进展OA

Selective oxidation of low-carbon polyols(derived from petroleum,coal or biomass)is a key approach for preparing high-value chemicals such as glycolic acid and glyceric acid.The development of efficient and green catalytic processes using molecular oxygen as the oxidant is of great significance for achieving high-value conversion of polyols and promoting the green upgrading of the high-end chemical industry chain.The core lies in the development of high-performance supported catalysts.In this paper,recent advances regarding the nano-gold catalysts with precise electronic effect modulation as the core for conversion of primary hydroxyl groups to carboxylic acids,secondary hydroxyl groups to ketones,and C—C bond cleavage to short-chain acids.It focuses on how support engineering and bimetallic synergistic strategies can address key issues such as selective activation of hydroxyl groups and inhibition of excessive oxidation by modulating the electronic structure of gold.The structure-activity relationships between electronic properties and catalytic performance are discussed,along with associated reaction mechanisms.Future directions for catalyst design and potential applications are also prospected,offering theoretical and practical guidance for the development of sustainable catalytic processes.
